Alstroemeria named Stalrobu

ABSTRACT

A new and distinct alstroemeria cultivar particularly distinguished by the generally light red-purple coloration of its very large flowers, the petals of which have a rhodamine purple body color overcase by a longitudinally extending central portion of a darker roseine purple color which presents a very unusual variegated color display. This new plant is further distinguished by its continuous and profuse blooming habit, its vigorous, strong and upright growth and by the excellent lasting quality of its blooms both on the plant and as cut flowers.

BACKGROUND OF THE INVENTION

This new alstroemeria cultivar originated as a seedling resulting frommy crossing of selected and individually identified plants maintained ingreenhouse at Aalsmeer, Holland, for breeding and developmentalpurposes. This particular seedling was selected by me because of thevery attractive red-purple coloration of its blooms, its profuseproduction of blooms and its apparent very fast and vigorous growthhabit and I reproduced this plant at Aalsmeer through root division withvery favorable results. Subsequently I carried that propagation throughseveral generations, thereby determining that the novel characteristicsof coloration and growth habit of this new plant would remain true fromgeneration to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

My new alstroemeria cultivar is illustrated by the accompanying fullcolor photographic drawing which shows a full umbel of the inflorescencewith buds and flowers in various stages of opening, the color renditionbeing as nearly true to those specified as is reasonably possible toobtain by conventional photographic procedures.

This alstroemeria cultivar is particularly distinguished by its verylarge and numerous flowers with variegated light red-purple colorationand by its profuse production of flowers on relatively long, strong,umbel stems.

I claim:
 1. The new and distinct variety of alstroemeria plant,substantially as herein shown and described, characterized by thedistinctive red-purple coloration of its large flowers carried bysturdy, long and generally straight umbel stems.
